The clouds were gathering darkly over the head of the gallant Vere; for no sooner had he arrived at this determination than he learned from a deserter that the archduke had fixed upon that very Sunday evening for a general assault upon the place. It was hopeless for the garrison to attempt to hold these outer forts, for they required a far larger number of soldiers than could be spared from the attenuated little army. Yet with those forts in the hands of the enemy there would be nothing left but to make the best and speediest terms that might be obtained. The situation was desperate. Sir Francis called his principal officers together, announced his resolve not to submit to the humiliation of a surrender after all their efforts, if there was a possibility of escape from their dilemma, reminded them that reinforcements might be expected to arrive at any moment, and that with even a few hundred additional soldiers the outer works might still be manned and the city saved. The officers English, Dutch, and French, listened respectfully to his remarks, but, without any suggestions on their own part, called on him as their Alexander to untie the Gordian knot. Alexander solved it, not with the sword, but with a trick which he hoped might prove sharper than a sword. He announced his intention of proposing at once to treat, and to protract the negotiations as long as possible, until the wished-for sails should be discerned in the offing, when he would at once break faith with them, resume hostilities, and so make fools of the besiegers.
This was a device worthy of a modern Alexander whose surname was Farnese. Even in that loose age such cynical trifling with the sacredness of trumpets of truce and offers of capitulation were deemed far from creditable among soldiers and statesmen, yet the council of war highly applauded the scheme, and importuned the general to carry it at once into effect.
